Validation analysis of PEROX risk score. Models were assessed for their association with 1-year incident risk of MI or death. Models were made up of traditional risk factors alone (including age, gender, smoking, LDL cholesterol, HDL cholesterol, systolic blood pressure, and history of diabetes mellitus) vs traditional risk factors plus PEROX score. Resampling (250 bootstrap samples from the validation cohort, n=1474) was performed. All data analyses, including ROC analyses and AUC determinations, were separately recalculated at each resampling for models with/without PEROX score. The AUCs calculated from the bootstrap samples are compared by the use of side-by-side box plots in which boxes represent interquartile ranges (defined as the difference between the first and third quartiles) and whiskers represent the 5th and 95th percentile values.
